​

IPTG is a biotech reagent for protein production, used during microbial fermentation to induce the expression of recombinant proteins controlled by lac operon.

​

As a molecular mimic of allolactose, IPTG is a non-hydrolyzable galactose derivative that induces transcription of the gene in lac operon by binding to and inactivating the lac repressor. Unlike lactose, IPTG is not metabolized by cells, thus eliminating the need for continuous monitoring of the inducer concentration during protein expression. Additionally, because IPTG concentration remains constant, high titer production and consistent protein expression of genes controlled by the lac operon can be achieved.

​

The optimum concentration of IPTG used for inducing protein expression should be empirically determined as it can depend upon multiple factors, such as the strength of induction required, cellular genotype, etc.

​

IPTG is also a commonly used inducer in conjunction with X-Gal in blue-white color screen for rapid identifying recombinant bacterial colonies.
